TreeWidget is something wrong.

[IWATA Hidetaka]

At 0.18.3(r1219), TreeWidget is something wrong.

One example can be reproduced by this steps:
----------
  bzr init test
  cd test
  mkdir foo
  echo foo > foo\foo.txt
  mkdir bar
  echo bar > bar\bar.txt
  bzr add foo\foo.txt
  bzr qcommit

  First, this tree is shown in qcommit dialog.
   foo
   + foo.txt

  After checking 'Show non-versioned files', wrong tree is shown.
   bar
   + foo <- wrong node
   foo
   + foo.txt
----------

I also saw similar behavior in qbrowse, but I can't reproduce it.

Version info:
Bazaar (bzr) 2.1.0
  Python interpreter: C:\Program Files\Bazaar\python25.dll 2.5.4
  Python standard library: C:\Program Files\Bazaar\lib\library.zip
  Platform: Windows-XP-5.1.2600-SP3

Regression caused by rev 1058.

Hi Gary,
Is it possible to add a test for that regression, to help pick it up in the
future?
I'm sure this treewidget is very complex and it pretty central to most of
the dialogs.

Thanks for the hard work.

Agree. I think that with out better tests, I'm going to lose my sanity...
